No single individual living in North or South America ever means anything other than "the United States" when they say "America."
Like how "Americans" means "residents of the United States," not "residents of Canada, the United States, Mexico, Trinidad, Tobago, Costa Rica, Nicaragua, Colombia, Argentina, French Guiana, Chile, etc, etc..."
Though the number of people automatically assuming this took place in the US in this thread is genuinely amusing, because it means people didn't read anything past the title before posting.
